In order for that to sound natural (and be grammatical), while keeping it as close to the way you phrased it as possible, you need to move the which toward the end of the sentence, add by in front of it, and drop the additional pronoun (I'm also going to add a comma, although it's not directly relevant to the syntax). Also note that it's not abide to but abide by.
✘ Her parents forced her into an arranged marriage the consequence of which if not abiding to it was death.
✔ Her parents forced her into an arranged marriage, the consequence of not abiding by which was death.
This works because it combines the elements of all of these constructions, along with a negation:
She abided by her marriage.
Marriage was the thing by which she abided.
The consequence of which was death.
The consequence of [not abiding by] which was death.
